Notes:
In metallic alloys, the formation of macrostructure involves different lengthand time scales. The macrostructure strongly influences the mechanical properties of thematerials. Modeling of macrostructure provides valuable insights for tailoring of themacrostructure. In the present study simulation of macrostructure in Al-22Sn has beencarried out. Expression for nucleation rate and growth rate were tuned to get a match withthe experimentally observed macrostructure. The study incorporates the motion of grainsdue to Brownian motion. Incorporation of Brownian motion resulted in more uniformdistribution locally, which has been experimentally observed. Both simulation andmacrograph showed few columnar grains and absence of sharp columnar to equiaxedtransition
